Abstract
A multilayer ceramic capacitor includes a glass component of an underlying electrode layer including Zr and Ba, and in a cross-section of the multilayer ceramic capacitor, a Zr/Ba atomic number ratio is not less than about 0.03 and not greater than about 0.15. The underlying electrode layer has a glass-occupied area ratio of not less than about 18% in the cross-section of the multilayer ceramic capacitor. In a SEM image in the cross-section of the multilayer ceramic capacitor, the glass component on an imaginary line α, which is parallel or substantially parallel to the surface of the surface layer of the underlying electrode layer about 3 μm inside of the surface layer of the underlying electrode layer, is not greater than about 0.92 μm.
